Definitions

  • the invention relates to a device for measuring rotationally symmetrical precision parts, preferably on CNC-controlled gear measuring centers for testing Stirnradverzahnept and cutting and Schabraten, screws and worm wheels, hobs, bevel gears.
  • the invention also relates to a clamping device for clamping the precision parts.
  • a coordinate measuring system which comprises a two-part turntable.
  • An upper plate of this turntable bears on balls that are rigidly mounted in conical recesses of a lower plate. These balls are mounted along the outer circumference of the lower plate in corresponding holes.
  • the upper plate has on its underside cylindrical rods which are directed radially. Placing the upper plate on the lower, so these rods are in V-shaped spaces, which are formed by each adjacent balls.
  • To rotate the upper plate with respect to the lower plate of the upper plate is raised and placed in a different angular position.
  • a device for measuring rotational parts with a clamping device is known, which is designed as a multi-jaw chuck.
  • the precision part can be removed from the processing machine and clamped in a special measuring system, where it is scanned and measured by means of sensors.
  • a special measuring system where it is scanned and measured by means of sensors.
  • numerically controlled measuring devices are used for this purpose.
  • a rotationally symmetrical precision part is clamped between a lower center point, which sits on a turntable of the measuring device, and an upper center point. It is also possible, however clamp rotationally symmetrical precision part on one side only on the turntable of the meter.
  • this application is about CNC-controlled gear measuring centers, which are used for testing spur gear teeth and cutting wheels, worms and worm wheels, hobs, bevel gears and general dimensional, shape and position deviations on rotationally symmetrical workpieces, for cam and camshaft measurement or Rotor measurement are suitable.
  • the object is achieved by a device according to claim 1 and a clamping device according to claim 10.
  • a first device 10 according to the invention (also called measuring center) is shown in FIG. Based on this figure, the environment is explained in which the invention can be used. Shown is a fully automatic, CNC-controlled gear measuring center 10.
  • the measuring center 10 is suitable for testing spur gear teeth and cutting and Schabckenn, worms and worm wheels, hobs, bevel gears and general dimensional, shape and position deviations on rotationally symmetrical workpieces, the curve and Camshaft measurement or for rotor measurement, to enumerate only a few applications.
  • the device 10 comprises a turntable 13 which can be driven via an actuator 12.
  • a rotationally symmetrical precision part 11 to be measured is clamped coaxially with respect to the axis of rotation A1, as indicated in FIG.
  • the control 12 comprises a drive and the control of the drive. Both are not visible in Fig. 1, since these elements are located behind a panel of the measuring system 10.
  • a probe or the like can be attached to a radial axis 14 in order to be able to measure the precision part 11.
  • the precision part 11 is clamped in a tensioning device 16.
  • This tensioning device 16 has an adapter (16.1) which sits on the turntable 13, as will be explained with reference to FIGS. 2, 3 and 4.
  • a pinion 11 can be clamped.
  • one half of the pinion 11 is indicated.
  • This pinion 11 is seated with its shaft between the clamping jaws 16.6 of the clamping device 16.
  • the arrow 18 is indicated that the clamping jaws 16.6 clamp by radial movement in the direction of the axis of rotation A1, the shaft.
  • the jaws 16.6 sit on a plate 16.4, which has a ring for manual operation 16.5.
  • the tensioning device 16 is similar to operating the chuck of a drill. By turning the ring 16.5 with respect to the plate 16.4, the jaws 16.6 are opened or closed.
  • This rotationally symmetrical precision parts (such as the pinion 11) can be clamped quickly and easily in any size and design.
  • the tensioning device 16 has an intermediate piece 16.3.
  • This intermediate piece 16.3 can for example be designed so that it can be easily grasped by hand or by a gripper of a feed device.
  • the intermediate piece 16.3, or the clamping device 16 in one embodiment without intermediate piece, sitting on an adapter 16.1.
  • This adapter 16.1 is equipped with means 16.2 (in the present example three balls 16.2) for centered recording on the turntable 13. On the turntable 13, three receiving means 13.1 are provided for receiving the means 16.2.
  • the adapter 16.1 can lie flat on the turntable in another embodiment (see also Fig. 4). In this case, 13 recesses for receiving the means 16.2 are recessed in the turntable.
  • a plan view of the turntable 13 is shown.
  • the position of the receiving means 13.1 and the means 16.2 can be seen.
  • the means 16.2 together with the receiving means 13.1 a so-called three-point storage.
  • the position of the tensioning device 16 together with the pinion 11 is precisely defined, i. the storage is concentric.
  • this storage allows precise torque transmission from the turntable 13 on the tensioning device 16 and the pinion 11th
  • a cylindrical wheel 11 is clamped concentrically with a shaft between the clamping jaws 16.6.
  • the clamping device 16 comprises, viewed from top to bottom, the clamping jaws 16.6, a plate 16.4, which has a ring for manual operation 16.5, and an adapter 16.1 (for example, an adapter plate).
  • This adapter plate 16.1 sits flat on the turntable 13.
  • the means for centered recording clamping device 16 on the turntable 13 are not visible in this figure. However, these means are designed so that the clamping device 16 and the precision part 11 are rotatably connected to the turntable 13 without slipping.
  • three balls may be provided in the adapter 16.1, which engage in recesses of the turntable 13. By a prismatic shape of the recesses, the situation is precisely defined.
  • the device 10 may also include a setup station to individually equip a plurality of fixtures with precision parts 11 before they are then placed one after the other on the turntable 13 and measured there.
  • a setup station to individually equip a plurality of fixtures with precision parts 11 before they are then placed one after the other on the turntable 13 and measured there.
  • This approach is particularly advantageous because different precision parts 11 can be clamped and thus prepared while a measurement is running. Then, after completion of a measurement, the precision part 11 together with the tensioning device 16 which has just been measured can be removed, and another precision part 11 can be placed with another tensioning device 16 and another adapter 16.1. This type of execution of the procedures can save considerable time.
  • the utilization of the measuring system 10 goes up.
  • Such a setup station may be present on the device 10 or externally and is particularly advantageous.
  • the device 10 comprises a feed device, which is designed so that a fitted with a precision part 11 clamping devices 16 can be moved from the setup station to the turntable 13 and placed there.
  • a feed device for example, a robot arm, or the like can be used.
  • the advantage of the invention is that the feeding device can always engage at the same point on the tensioning device 16 (for example on the intermediate piece 16.3). This makes the execution of the feeder easier.
  • the invention is particularly suitable for fully automated CNC measuring equipment 10 for measuring gears 11.
  • CNC measuring device can be measured in addition to externally toothed spur gears and internal gears, bevel gears, screws, gear tools and the like.
  • a variant is shown in which a ball is 16.2 in a receptacle 13.1 with V-shaped cutout. If three such receptacles 13.1 are provided with balls 16.2 on the turntable 13, the adapter 16.1 sits centrally on the turntable 13.
  • a variant is shown in which a ball 16.2 is supported by two smaller balls 13.2 sitting in a receptacle 13.1. Also by such an arrangement, a centered mounting of the adapter 16.1 can be achieved on the turntable 13.
